Our Process
Stop Leaks Where They Start
Guttering and downpipes increase the flow of water and stop it pooling, so we detail drainage as carefully as the membrane.
01
Inspect
We check joints, drains and the finish for where water gets in.
02
Prepare
Surfaces cleaned and primed, with butyl tape or gauze at risky joints.
03
Apply Membrane
A membrane that bonds to the substrate without gaps.
04
Test & Warranty
Flood tested and backed by our 7-year warranty.
